Hi folks!

I'm new to ConTeXt and right now playing around with its minimal distribution (MkIV).
Trying to tinker with my very first typescript I have downloaded the ZIP archive
of fourier-GUT fonts from CTAN and extracted the afm and pfb files into a new
directory on the OSFONTDIR path and updated the ConTeXt font cache.
Looking at the typescript definition of "fourier" in "type-one.mkii"
and using the other samples on ConTeXt wiki pages I produced the following typescript:

An immediate test has shown that unfortunately the math part of a short sample text
isn't displayed properly. I have also tried it using "ec" and "default" instead
of "texnansi" (cf. \starttypescript [math] [fourier][texnansi]) with a similar
result (in these cases except a Greek letter all of math part is missing
in the pdf output).

I'm using ConTeXt/LuaTeX version 2010.09.27 on (Arch)linux 64bit.

Any help or suggestion is very much appreciated!

Best regards
Nik
